Let's see, when faced with the choice to:
A: Concede that calling the sun "cold" was a poor choice of words...
or
B: Refuse to make the smallest of concessions and stand fast that the sun is indeed, cold
You chose the latter.
And I am the childish one?
The sun is not cold Fitz. It doesn't get cold. Not even metaphorically does the sun get cold. It is synonymous with "hot". Not even in relative terms does the sun ever become "cold'. it has subtle variations based on sun spots.
If we had a branding iron that said "stubborn as a mule" and we stuck it in the fire until it was red hot and then stuck it to Fitz butt, he would surely say it was hot. If we cooled it by the same margin as sun spots cause the sun to cool and stuck it again to Fritz butt, he would surely not say that it was now cold. In fact, it would still be terribly hot. You might call it "not as hot" or "still dang hot" or even "my God, that is still hot" but no sane person would say "my, that burning sensation sure is cold!"
The sun is not cold. It is hot. Even when the sun's temperature goes down, even when when this relatively slight cooling takes place, it is not the vast degree of temperature difference that signifies even relatively "cold".
This is basic.
The sun is not cold.
